Main Document

This resource is a collection of EJS (Easy Java Simulation) models of electrostatics. Students can move charges around and see the force, observe the electric field generated by charge configurations, and observe the motion of test particles in electric fields. Also included are instructor's guides and student worksheets to supplement the simulations (See "Documents" for supplementary materials.)

Editor's Note: This package was created for use in middle school and 9th grade physical science, but the models can easily be adapted for high school physics courses. SEE ANNOTATIONS for additional content support on Coulomb's Law and charge interactions.

This item was created with Easy Java Simulations (EJS), a modeling tool that allows users without formal programming experience to generate computer models and simulations. To run the simulation, simply click the Java Archive file below. To modify or customize the model, See Related Materials for detailed instructions on installing and running the EJS Modeling and Authoring Tool.
